hi guys, newbie here, please be gentle :) the battery in my 96 widebody camry went flat, so ive changed the battery in it that has a OEM Pioneer premium sound system with security PIN feature. (double DIN tape deck with 6 stacker) the security feature activates when there is no power source problem is we've forgotten the PIN number for the pioneer system. is there a way to reset it or turn it off without taking it to Toyota and getting charged for it? help appreciated thanks
